multiselect in treetable doesn't work with 1000 entries

When I have 1000 entries in treetable, if I select the first item and use the key “shift” in last item, browser is down and said us to wait because a script is executed , is it normal ? (In firefox and IE11)

Thanks

Hi,

Nope, this is not expected behavior.
Please check do you have custom event handlers for onBeforeSelect / onAfterSelect
Such handlers will be called for each item, so if you have some heavy code there, it can slowdown rendering a lot.

If issue still occurs for you, can you please share a snippet where it can be reconstructed, as selection works relative fast for me in local samples
